WINDMILL.

SPECIFICATION forming part of Letters Patent No. 321,760, dated July 7,1885.

Application filed April 16, 1885. (No model.)

To all whom, it may concern.-

Be it known that l, ALFRED L. SHERRED, a citizen of the United States,and a resident of Venango, in the county of Crawford and State ofPennsylvania, have invented certain new and useful Improvements in\Vindmills; and I do hereby declare that the following is a full, clear,and exact description of theinvention, which will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, which form a part of thisspecification, and in which- Figure 1 is a side View of my improvedwindmill. Fig. 2 is a front view of the same. Fig. 3 is a longitudinalvertical sectional view taken on the line a: 00 in Fig. 4. Fig. 4 is atop view, part of the framing having been broken away for the purpose ofshowing the construction more clearly; and Fig. 5 is a top view taken onthe line 00 cc of Fig. 1, showing the pivoted bar.

The same letters refer to the same parts in all the figures.

This invention relates to windmills; and it has for its object toprovide a device which shall possess superior advantages in point ofsimplicity, durability, and general efliciency. lVith these ends in viewit consists in the improved construction, arrangement, and combinationof parts, which will be hereinafter fully described, and particularlypointed out in the claims.

In the drawings hereto annexed, A designates a base or turn-table havinga vertical tubular post, B, on which is journaled a tube or sleeve, 0,the upper end of which carries a bracket, D, the rear end of which isprovided with a vertically-disposed tail-vane, E, secured rigidly in thesaid bracket.

The front end or arm, F, of the bracket D is provided with asuitablebearing for a horizontal longitudinal shaft, G,which is tubular,as shown, and the inner end of which is provided with a crank, H,connected by a pitman, l,with a vertically-reciprocating rod, J, whichis suitably connected with the pump or other machinery to be operated.

K is a hub or collar arranged to slide longitudinally upon the inner endof the shaft G, and having a lug or stud, L, extending inwardly into thecentral tubular portion of the said shaft G through a longitudinal slot,M, in the latter. The said lug L is connected by a rod, N, extendinglongitudinally through the shaft G,with a lug, 0, extending inwardlyfrom a hub or collar, P, arranged to slide upon the outer end of thelatter, the said lug 0 extending through a diagonal slot in the saidshaft, as shown. It will be seen by this arrangement that when the hubor collar P is caused to slide upon the shaft, it will at the same timehave an oscillating motion upon the latter, the object of which will bepresently more fully explained.

Q is a hub or collar mounted firmly upon the shaft G, and provided witha series of pivoted radiating arms, It It, carrying the vanes S S, andhaving hinged forwardly-extending arms T T. The ends of the said armsare connected by pivoted rods U U with rods V V, extending radially fromthe hub or collar P, as will be clearly seen in the drawings.

W W are a pair of regulating-vanes, the arms or shanks of which arepivoted in a vertical slot, X, in the tail-vane E, and provided withforwardly-extending pivoted rods Y and Z, which are connected by apivoted bar, A, and the former of which, Y, is connected pivotally withthe arm B of a rock -shaft, 0, mounted transversely upon the frame orbracket D. The said rock-shaft has an up wardly-extending arm, D, theupper end of which is forked at E and engages an annular groove, F, inthe hub or collar K. The said rod Y is also connected, pivotally, withone arm of a bell-crank lever, G, pivoted to the bracket D, and havingan inwardly-extending arm, H, to which is connected an operating rod orcord, 1, which extends downwardly through the tubes B G to some pointfrom whence it may be conveniently manipulated.

I J is an arm or lever pivoted to the side of the tail-vane E, andcarrying at one end an adjustable weight, K, its other end beingconnected by a pivoted rod, L, with the arm Y.

From the foregoing description, taken in connection with the drawingshereto annexed, the operation and advantages of this invention will bereadily understood.

The tail-vane E will serve to keep the wheel to the wind. When the windincreases in strength or force, it will tend to force the wheel-vanesfrom their diagonal position, presenting their edges to the wind, thisbeing partially effected by the direct pressure of the wind upon thevanes, and partially by its forcing the regulating-vanes in a rearwarddirection, thus causing the intermediate mechanism, which has beenherein fully described, to twist or turn the regulating-collar 1 uponthe shaft G in such a manner as to turn the vanes. The speed maylikewise be regulated by simply pulling the cord I, thus throwing theoperating and regulating vanes out of the wind. The weight K, upon theend of the arm or lever J, serves to assist in restoring the vanes totheir original or normal position.

Having thus described myinvention, I claim and desire to secure byLetters Patent of the United States- 1. In a windmill, the combinationof the horizontally-revolvi ng frame, the tubnlarshaft journaled in thesame and having a straight and a diagonal slot, respectively, near itsrear and its front ends, a sliding hub having a lug or stud extendingthrough the straight slot, a sliding hub having a lug extending throughthe diagonal slot, a rod connecting the said lugs, a stationary collarhaving pi voted vanes, rods connecting the shanks of said vanes with thefront sliding collar, and mechanism eonnecting the rear sliding collarwith the regulating-vanes, substantially as and for the purpose setforth.

2. In a windmill, the combination of the revolving frame or bracket, thetubular shaft, the stationary collar or hub having the pivoted vanes,the sliding adjusting-collars eonnccted by a rod extending through thelongitudinal tubular shaft, the stationary vertical tail vane, thehorizontal regulating vanes hinged to the latter, forwardly-extendingrods pivoted to the shanks of said regulating-vanes, a rock-shaft havingarms connected with one of said rods and with an annular groove in therear adjusting collar, an adjusting bell-crank connected with said rod,and aweighted lever connected by a pivoted arm with the said vane-rod,substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereuntoaffixed my signature in presence of two witnesses.

ALFRED L. SHERRED.
